usb: typec: ucsi: Delay alternate mode discovery

Browse Source 
Delay the ucsi_check_altmodes task to be inline with surrounding partner
tasks. This allows partner, cable and identity discovery to complete
before alternate mode registration. With that order, alternate mode
discovery can be used to indicate the ucsi driver has completed
discovery.
